Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the invention is to provide a driving device which can avoid electric wiring. The other core of the invention is to provide a multi-station rotary platform comprising the driving device, which can avoid excessive and complicated electric wiring, simplify an electric structure and save equipment cost.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of a driving device provided in the present invention; fig. 2 is a schematic structural diagram of an embodiment of a multi-station rotary platform according to the present invention.

The invention provides a driving device, which comprises a rotating part 1 for arranging a workpiece or a cutter, a linear driving device 2 for providing power input for the rotating part 1, and a transmission part for converting the linear motion of the linear driving device 2 into the rotary motion of the rotating part 1, wherein the linear driving device 2 outputs linear motion, the output end of the transmission part is fixedly connected with the rotating part 1, and the input end of the transmission part can be connected with and separated from the output end of the linear driving device 2.

It should be noted that the rotating member 1 is used for arranging a workpiece or a tool to drive the workpiece or the tool to rotate, and mainly plays a role in fixing and supporting the workpiece or the tool. For example, the rotating member 1 may be a tool holder, and the tool holder may be used for setting a tool or inserting a workpiece.

The present invention is not particularly limited to the specific structure and operation form of the linear drive device 2, as long as it can output linear motion. For example, the linear driving device 2 may be a cylinder, a hydraulic cylinder, a linear module, or the like.

Further, the present invention does not specifically limit the specific structure and transmission form of the transmission member, and any mechanical transmission structure may be used as long as the mechanical transmission structure can convert linear motion into rotational motion.

The invention is characterized in that the output end of the transmission piece is fixedly connected with the rotating piece 1, and the input end of the transmission piece is connected with and separated from the output end of the linear driving device 2.

It can be understood that, when the input end of the transmission member is connected with the output end of the linear driving device 2, the linear motion output by the linear driving device 2 can be transmitted to the rotating member 1 via the transmission member, and then the linear motion output by the linear driving device 2 is converted into the rotating motion of the rotating member 1 under the action of the transmission member, so as to drive the workpiece or the tool to rotate.

When the input end of the transmission member is separated from the output end of the linear driving device 2, the transmission member is separated from the linear driving device 2, the transmission member and the linear driving device are not affected by each other, and the interference of the further movement of each other can be avoided.

Therefore, in line work or multi-station turntables, a linear drive 2 is provided at a station to which a plurality of rotary members 1 and transmission members can be moved in sequence to effect rotary movement of a plurality of different rotary members 1 at the station by means of one linear drive 2. That is, when one of the rotating members 1 and the transmission member move to the station, the rotating member is connected with the linear driving device 2, the transmission member is driven to move by the linear driving device 2, and the linear motion of the linear driving device 2 is converted into the rotating motion of the rotating member 1; after the rotating member 1 completes the rotating motion, the rotating member 1 can be driven and the driving member can be driven to separate from the linear driving device 2, so that the linear driving device 2 can avoid interfering the next motion of the rotating member 1, and the next rotating member 1 can drive the driving member to be connected with the linear driving device 2 conveniently.

In addition, in assembly line operation or a multi-station turntable, the linear driving devices 2 are respectively arranged at a plurality of stations, a plurality of rotating pieces 1 and transmission pieces can sequentially and respectively move to the stations provided with the linear driving devices 2, so that each rotating piece 1 can complete rotating motion at each station provided with the linear driving device 2, and further, the corresponding processing of each station is realized.

The connection of the transmission element to the linear drive 2 can also be realized by means of a clamp, which is released when the two need to be separated.

In summary, in the driving device provided by the present invention, the linear motion of the linear driving device 2 is converted into the rotational motion of the rotating member 1 through the transmission member, and compared with the prior art in which the motor is used to drive the rotating member 1 to rotate, the electric wiring can be avoided.
